VAPOR-LAM P.

SPECIFICATION formingpart of Letters Patent No. 636,935, dated November14, 1899.

Application filed February 14:, 1899. Serial No. 705,503. (No model.)

To all whom it may concern.- Be it known that we, GEORGE WOLKE and HARRYD. 'EASTERLY, citizens of the United States, residing at Jacksonville,in the county of Morgan and State of Illinois, have invented new anduseful Improvements in Vapor- Lamps, of which the following is aspecification.

This invention relates to an improved gasolene-lamp, and especially tothat class wherein the vaporfrom the gasolene is drawn up by capillaryattraction to a point where the gas is generated and directed to andthrough a pipe to the burner, the burner after the lamp isstartedperformin g a double function-viz. lighting and heating the vaporto generate gas.

The object of this invention is to produce alamp which is simple inconstruction, effective in operation, and one capable of being handledby the most unskilled individuals. The manner in which we produce theseresults and the details necessary to carry them out will be described,and pointed out in the claim.

In the drawings, Figure 1 is a view of our improved lamp. Fig. 2 is aplan view thereof.

The same numerals refer to like parts in both figures.

1 indicates a supportwhich may be formed as shown in full lines or maybe a wall-bracket, as shown in dotted lines, or, if so desired, the lampcan be supported by achain from the ceiling, asindicated at 2. However,the question of support forms no special part of our invention.Sufficient to say, any well-kn own means may be employed.

A tank 3, preferably in the form of a globe, is provided, into the upperpart of which enters and extends to within a short distance of thebottom the fluid-conducting tube 4. The tube and arrangement thereofform a very important part of this invention. The tube is bent at ananglej ust outside the tank, as at 5, then given another bend in avertical direction, as at 6, and then bent in at the top, as at 7. Thisportion 7 forms the retort and has a slight extension 8 in the oppositedirection to provide for a needle-valve 9 and stuffing-box 10.

The needle-valve is of ordinary construction,

having the usual finger-piece 11 and reduced needle-point 12, the latterfitting in a valveseat 13 at the inner reduced end of the pipe sectionor retort 7. Extending in an opposite direction to the bend 5 of theconducting-tube 4 and on a plane to the same is the integrallyformedhorizontal tubular portion 14 of a gassupply pipe 15, which has averticalportion 16 and an upper inturned or horiz'ontalportion 17. Theinner end of the lower horizontal portion is extended up to form a shortvertical section 18, to which is applied the burner 19. The inner end ofthe upper section 1? is open, and the end of the needle-valve ispresented to said open end.

The ends of the chain 2 are secured to the upper ends of the pipes, asclearly shown.

The tank 3 is provided with a filling-opening 21 and a cap 22. Thisopening is situated slightly below the top of the tank, so as to providean air-space. A check-valve is also provided in the upper part of thetank and has connected to it a short section of pipe 24., having a bulb25 at the outer end to be used for forcing air into the tank to forcethe gasolene out, as shown.

Awick is placed in the conducting-pipe, so as to conduct the gasolene upto and within the valve chamber or retort.

By reference to the drawings it will be seen that the pipes arepractically one, the upper part, or that above the tank, forming aburner frame or support. The lower T end is screwed into the tank andaffords means for conducting and limiting the amount of vapor, the twopassageways being separated by a partition 26. This manner ofconstructing the frame of the lamp is extremely simple and practical,forming a rigid structure throughout, and especially at the point ofunion of the tubes '5 and let, at which point they are formed integral,as by casting or otherwise. This we consider as being an essential andimportant feature of our invention.

The operation of the lamp, it is thought,wi1l be readily understood. Thegasolene is carried by capillary attraction and by force of the air inthe top of tank to and through the Wick, the vapor accumulating in theretort. Before lighting the lamp the needle-valve is opened and the bulbis squeezed several times, forcing the vapor through the conductingtubeand out through the valve-opening into the open end of the pipe-section17 and thence to the burner. A light is now applied, whereupon the flamewill heat the retort or valve chamber and the vapor therein, causing ageneration of gas,'wh'ich passes through the pipe 16 to the burner.

Having thus described our invention, what we claim is In a gasgeneratinglamp, the combination with an oil-tank, of an oil-conducting pipe havinga connection with the tank and extending therein to near its bottom,said pipe being directed outward in a horizontal direction at the pointwhere it leaves the tank, and then extended upward in a verticaldirection and having its extremity reduced in diameter and directedinward in a horizpntal plane immediately above and parallel with thelower horizontal portion of the pipe, said reduced end being providedwith an opening and a needle-valve cooperating therewith,and agas-conducting pipe formed integral with the said oil-pipe at the pointWhere the latter leaves the tank and provided with a shortupwardly-extending central portion adjacent to its point of connectionwith the said oil-pipe,

and horizontally and vertically extending portions arrangeddiametrically opposite the corresponding portions of the oilconductingpipe, the extreme end of said vertical portion of the gas-pipe beingopen and directed inward and terminating at a point adjacent to the saidneedle-valve opening in the oil-conduct ing pipe, and a burner carriedby the said short upwardly-extending portion of the gaspipe and locateddirectly below the said contracted portion of the oil-conducting pipe,the parts being arranged and cooperating substantially as described.

In testimony whereof We have hereunto set our hands in the presence ofthe subscribing witnesses.
